Equipment 400 may include air interface structure block selecting unit (AIBBSU) 405, can be used for from each structure block of selection A kind of option is selected in available multiple possible options for each structure block of air interface.AIBBSU 405 can be wanted according to transmission 410 are asked to select option for structure block.In other words, AIBBSU 405 can be selected from candidate air interface according to transmission requirement 410 Air interface.Transmission requirement 410 may include transport-type (that is, transferring content), such as voice, video, music, data, sensing Device data, telemetry, multimedia, game data etc., these can correspond to the transmission of low time delay susceptibility, middle time delay sensitivity Transmission, the transmission of high time delay sensitivity, low fault-tolerant transmission, in fault-tolerant transmission, high fault-tolerant transmission, parcel transmission, big packet transmission etc..
Transmission requirement 410 may also include other requirements, such as data rate, serious forgiveness, in real time limitation, quality of service requirement Etc..Transmission requirement 410 may also include transmission condition, can be the letter in relation to communication equipment centering as the equipment of transmitter Breath.The example of transmission condition can include: transmitting antenna number, available transmission resources, available computational resources, the channel at transmitter Condition etc..The other examples of transmission condition can include: low PAPR tolerance, high PAPR tolerance, low-processing-power receiver, High disposal power receiver, low time delay extension, high delay spread etc..Transmission requirement 410 may also include condition of acceptance, can be Information in relation to communication equipment centering as the equipment of receiver.The example of condition of acceptance can include: receiving antenna number can be used Channel condition, UE at computing resource, receiver assist reception, non-UE to assist reception etc..
Transmission requirement 410 can be sorted out in unit 415 in transmission requirement and sort out to obtain the classification version of transmission requirement 410. Since the range of the probable value of transmission requirement 410 may be very wide, transmission requirement, which sorts out unit 415, to be transmitted by characterizing It is required that 410 reduce complexity associated with the large-scale probable value.As illustrated examples, a kind of situation is considered: passing It is defeated that the 410 middle time delay sensitivity including time delay range less than 100ms is required to transmit.Transmission requirement sort out unit 415 can pass through by Transmission requirement 410 is classified as middle time delay sensitivity transmission classification of the time delay range within 20ms to 100ms to simplify transmission requirement 410.In other words, transmission requirement sorts out unit 415 by sorting out the sky thought for sending transmission to the transmission requirement 410 of transmission Each structure block of middle interface simplifies the selection of option.
Equipment 400 is also using the option of each structure block (or in brief, option) 420.Option 420 can be determined in advance And it is stored in the addressable memory of AIBBSU 405.It can determine option 420, in this way obtained by the subset of selection option 420 Air interface can meet transmission requirement 410 a series of desired values performance standard.As illustrated examples, option 420 First subset (can be described as the first candidate air interface) can obtain the air interface for meeting the performance standard of transmission requirement 410, should Transmission requirement 410 specifies middle time delay sensitivity transmission of the time delay range within 50ms to 100ms, and the second of option 420 is sub Collection (can be described as the second candidate air interface) can obtain the air interface for meeting the performance standard of transmission requirement 410, which wants The parcel for the 5kbps for asking 410 specified error rates extremely low transmits, and the third subset of option 420 (can be described as third candidate to connect in the air Mouthful) air interface for meeting the performance standard of transmission requirement 410 can be obtained, which specifies the big packet of 2Mbp to transmit But tolerable long time delay.Alternatively, the external entities such as the operator of network entity, communication system, technical standard can determine option 420。
Equipment 400 is also using the mapping 425 between option 420 and the possibility classification of transmission requirement 410.Mapping 425 can The subset of specified which option 420 when selecting option 420 for the structure block of air interface will meet classification transmission requirement 410. AIBBSU 405 can determine mapping 425.Mapping 425 is storable in memory for subsequent use.Mapping 425 can be with look-up table Etc. sheet formats stored, the table by sort out transmission requirement 410 be indexed.In other words, AIBBSU 405 can be each Structure block selects multiple options 420 to meet different classes of transmission requirement 410.For example, multiple choosings may be selected in AIBBSU 405 420 transmit the air interface of the performance requirement of classification with time delay sensitivity in being met.Alternatively, network entity, communication system The external entities such as operator, the technical standard of system can determine reflecting between multiple options 420 and the classification version of transmission requirement 410 Penetrate 425.
The class that table 1 shows transmission requirement 410 is clipped to the example mappings of option 420, and wherein transmission requirement 410 includes transmission Content (for example, transport-type).The class that table 2 shows transmission requirement 410 is clipped to the example mappings of option 420, wherein transmission is wanted Asking 410 includes transmission and/or condition of acceptance.It should be noted that the blank entry instruction in table 1 or table 2 can be used for corresponding to structure block Discretionary choices or default option.
Table 1: mapping of the transferring content to structure block option
Table 2: the mapping of condition to structure block option is sent
Transmission requirement sorts out the output (the classification version of transmission requirement 410) of unit 415 and mapping 425 is provided to AIBBSU 405, AIBBSU 405 can select choosing according to each structure block that the classification version of transmission requirement 410 is air interface ?.Group be combined into the selected option of each structure block with it is specified will be used to sending meet the transmission of transmission requirement 410 and connect in the air Mouthful.As illustrated examples, if the classification version of the transmission requirement 410 of transmission is " low time delay susceptibility ", AIBBSU 405 can refer to mapping 425 (example of mapping 425 is shown in table 1) and to be intended for sending the air interface of transmission Frame structure structure block select long TTI, for retransmission technique structure block selection only ARQ, for actively coding and modulation technique structure block Select positive coded/modulated.Default option can be set by other structure blocks of air interface.As another illustrated examples, If the classification version of the transmission requirement 410 of transmission is " UE assists to receive ", AIBBSU 405 can refer to mapping 425 and (reflect 425 example is penetrated to be shown in table 2), and to be intended for sending the choosing of the retransmission technique structure block of the air interface of transmission Only ARQ is selected, selects hierarchical modulation for coding and modulation technique structure block.Other structure blocks of air interface can be set as defaulting Option.
It should be noted that a kind of technology is emphasized in the discussion of Fig. 4, wherein AIBBSU 405 is simultaneously according to the transmission requirement 410 of classification Each structure block of air interface selects option.It is similarly to select a candidate from multiple candidate air interfaces and connect in the air Mouthful.However, AIBBSU 405 may select an option for each structure block of air interface, it is every time a structure block selection Option and the option that can have previously structure block selection, the selection of the subsequently selected structure block of the structure block potential impact Available options in journey.Under in such a configuration, the option selection of the structure block of air interface can follow tree.

Operation 500 can begin at equipment and generate the transmission condition of (predefined) transmission, condition of acceptance and/or transferring content Possible class is clipped to the mapping (box 505) of structure block option.The example of transmission requirement may include transferring content, transmission condition, connect Receipt part etc..Mapping can provide optimal air interface for the possible classification of each of transmission requirement.Equipment can be constructed by selection The option of block generates mapping to generate the possibility transmission condition, the air interface of condition of acceptance and/or transferring content that meet transmission. In other words, equipment can be candidate aerial for the possible classification configuration of each of transmission condition, condition of acceptance and/or transferring content of transmission Interface.The generation of mapping can priori execute and store in memory, such as use in the subsequent use of equipment.
Alternatively, mapping can be generated and provided to by different entities such as network entity, the operator of communication system, technical standards Equipment.For example, mapping can store in the server.For another example mapping can be transmitted to equipment.It should be noted that mapping can periodically more Newly or when event occurs update.The example of event may include the failure of the instruction for receiving more new mappings, one or more transmission To meet its respective performance standard, the error rate (such as frame error rate, the bit error rate, Block Error Rate etc.) for meeting particular value, network The significant change of topology, the significant change of number of devices, the significant change of type of service, more than one equipment are (such as eNB, micro- Microcell, RRH etc.) failure etc..More new mappings allow the operating condition changed, network congestion, business model etc..
Equipment can receive the ability information (box 510) of transmission receiving device.The ability of transmission receiving device can select It plays a role during air interface.For example, if transmission receiving device is not available relative complex coding and modulation skill Art provides the processing power of decoding encrypted transmission, then equipment, which can decide not to select, utilizes the aerial of complicated coding and modulation technique Interface.
Equipment can determine transmission sending device and transmit the transmission condition of transmission between receiving device, condition of acceptance and/ Or transferring content (box 515).Transmission condition, condition of acceptance and the transferring content of transmission can be classified as in multiple transport-types It is a kind of.When equipment is that the transmission selects air interface, the transmission condition of transmission, condition of acceptance and/or transferring content (and are passed It is defeated itself) information of transmission requirement for needing to meet about equipment is provided.If equipment is transmission sending device, equipment is known Know transferring content and send condition, and transmits purpose equipment to provide condition of acceptance information to equipment.If equipment is not to pass Defeated sending device, then transmission sending device can provide transferring content to equipment and send condition, and transmitting receiving device can Condition of acceptance is provided to equipment.
Transmission condition, condition of acceptance and/or the transferring content of transmission can be sorted out (box 520) by equipment.Transmission Transmission condition, condition of acceptance and/or transferring content can be classified as one of multiple transport-types.Condition will be sent, receive item Part and/or transferring content (and transmission) carry out sorting out the probable value that can reduce transmission condition, condition of acceptance and/or transferring content Larger range, to reduce complexity associated with the option of each probable value of selection.In other words, by transmission condition, connect Receipt part and/or transferring content carry out sorting out the search space for reducing the selection of structure block option.
Equipment can be according to the condition of transmission, condition of acceptance and/or transferring content classification and the transmission condition of transmission, condition of acceptance And/or the possibility class of transferring content is clipped to each structure block selection best option for being mapped as air interface of structure block option (box 525).It is each structure block of air interface that transmission condition, condition of acceptance and/or transferring content classification, which can be used, in equipment Select option.In other words, the transmission requirement sorted out can be used to select an air interface from multiple air interface candidates for equipment. For example, it is contemplated that the possibility class of the transmission condition of the transmission arranged as shown in table 1 or table 2, condition of acceptance and/or transferring content It is clipped to the mapping of structure block option, equipment can be used transmission condition, condition of acceptance and/or transferring content classification in table 1 or table 2 Scan for the structure block option to select air interface.
